8. The Dream Lord
Who Played Him? Toby Jones
When Did He Appear? Series 5 Episode 7 Amys Choice This version of the Doctor riffs a little on bit on the Valeyard in that theyre both manifestations of the Doctors dark side but theres a lot to the Dream Lord that sets him apart from the Valeyard. While the Valeyard is more restrained, keeps his villainy subtle, and uses Gallifreyan law as an excuse for his actions, the Dream Lord completely lets himself loose and goes all Bond villain, torturing the Doctor in as elaborate ways as he can instead of straight up killing him. Which not only allows for a great episode but also fits perfectly with his identity as part of the Doctors psyche. The frequent quips and overall hamminess of Toby Jones' performance including his multiple costume changes is an excellent counterpoint to Matt Smiths Doctor, and makes him a very effective villain. Even if the revelation that his manifestation was caused by some kind of previously unseen psychic pollen is a big copout.
